###### Appendix 1 to ETSO-C26d – Minimum Performance Standard for aircraft wheels, brakes and wheel/brake assemblies for small airplanes and rotorcraft *ED Decision 2016/029/R* This appendix prescribes the Minimum Performance Standard (MPS) of SAE ARP5381, ‘Minimum Performance Recommendations for Part 23, 27, and 29 Aircraft Wheels, Brakes, and Wheel-Brake Assemblies’, dated October 2000, as modified in this ETSO. Additions to and one deletion from the standard, are shown in italics as follows: *Additions:* *1. Page 3, a new paragraph is added after 3.6:* *Suitable Tire for Brake Tests, TT**BT* *TT**BT* *is the rated tyre type and size.* *TT**BT* *is the tyre type and size that has been determined as being the most critical for brake performance and/or energy absorption tests. The TT**BT* *must be a tire type and size approved for installation on the wheel (TS**WR**). The suitable tyre may be different for different tests.* *2. Page 7, a new paragraph is added after 4.3:* *Fire Protection: Except for small parts (such as fasteners, seals, grommets, and small electrical parts) that would not contribute significantly to the propagation of a fire, all solid materials used must meet the applicable flammability rules for the part and category of aircraft.* *Deletion:* *1. Page 13, paragraph 5.3.3.2 is disregarded. Worn brake testing is not a requirement of Part 23, 27 or 29, so it cannot be included in this TSO.* [Amdt ETSO/12]
